ACI A/RH-TEMP Series Relative Humidity/ Temperature Combinations

Relative Humidity/ Temperature Combinations
A/RH-TEMP Series

The A/RH-TEMP Series Relative Humidity transmitters, convert a resistance to a linear 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC output. The current signal may be transmitted over long distances on unshielded twisted-pair wire and will not be affected by the lead wire resistance orelectrical noise.
The Advanced Ceramic Technology design overcomes the limitations of other resistance-based humidity sensors that utilize water soluble polymer coatings. The Advanced Ceramic Technology enables these sensors torecover fully from condensation. This allows the sensor to maintain its accuracy over a longer period of time. Despite its accuracy, the Advanced
Ceramic Technology sensor and related circuitry is economical.
Accuracy is maintained over the entire operating range, using a thermistor for temperature compensation.
Each A/RH-TEMP Series humidity transmitter is calibrated using an NIST Traceable Temperature and Humidity Chamber.
